A humidifying and ventilating indoor unit of an air conditioner, comprising an air outlet duct (15) of a crossflow impeller and an air outlet duct wall (14) of the crossflow impeller. An air drafting opening (9) is provided on the air outlet duct wall (14) of the crossflow impeller. The air drafting opening (9) is perpendicular to the axis line of the crossflow impeller of the indoor unit. The clockwise angle (102) between a projected line of the air drafting opening (9) in a projection plane perpendicular to the axis line of the crossflow impeller of the indoor unit and on which an air outlet (16) of the indoor unit is located at the lower left side and the positive direction segment of a tangent to the air outlet duct wall (14) with the point at where the air drafting opening (9) intersects the air outlet duct wall (14) serving as an upper point of tangency (A) is greater than or equal to 15° and less than or equal to 180°. An air drafting pipe (7) is connected onto an indoor unit water drainage pipe (11). The pipe opening of the other extremity of the air drafting pipe (7) is connected to the air drafting opening (9) provided through the air outlet duct wall (14) of the crossflow impeller. The indoor unit is capable of drafting outdoor air, humidifying indoor air, recycling cooling capacity, and increasing the temperature and volume of air output of the indoor unit. |
